Answer 2

As the fertilized egg grows, a water-tight sac forms around it, gradually filling with fluid. This is called the amniotic sac, and it helps cushion the growing embryo.

The placenta also develops. The placenta is a round, flat organ that transfers nutrients from the mother to the baby, and transfers wastes from the baby.

A primitive face takes form with large dark circles for eyes. The mouth, lower jaw, and throat are developing. Blood cells are taking shape, and circulation will begin.

By the end of the first month, your baby is about 1/4 inch long - smaller than a grain of rice!



Month 2

Your baby's facial features continue to develop. Each ear begins as a little fold of skin at the side of the head. Tiny buds that eventually grow into arms and legs are forming. Fingers, toes and eyes are also forming.

The neural tube (brain, spinal cord and other neural tissue of the central nervous system) is well formed. The digestive tract and sensory organs begin to develop. Bone starts to replace cartilage. The embryo begins movement although the mother can not yet feel it.

By the end of the second month, your baby, now a fetus, is about 1 inch long, weighs about 1/3 ounce, and is virtually all head (1/3 of its body is head).



At about 6 weeks, your baby's heartbeat can usually be detected.

Month 3

By the end of the third month, your baby is fully formed. Your baby has arms, hands, fingers, feet and toes and can open and close its fists and mouth. Fingernails and toenails are beginning to develop and the external ears are formed. The beginnings of teeth are forming. Your baby's reproductive organs also develop, but the baby's gender is difficult to distinguish on ultrasound. The circulatory and urinary systems are working and the liver produces bile.

At the end of the third month, your baby is about 3-4 inches long and weighs about 1 ounce.



Since your baby's most critical development has taken place, your chance of miscarriage drops considerably after three months.

its different for everybody, but i this is about the time the little lady starts to feel the effects of the pregnany the most. the baby is moving like crazy, mom wants the baby out, baby wants out, braxton hicks contractions are like kicking in, they are like practice contractions, but further apart, and the baby is pretty much fully developed besides the skull which sometimes doesnt fully develop even after birth.i took a 4dimensional ultrasound of my baby in the womb around this time and you could see everything, even the face. its amazing.

Brown discharge is many times previous blood, like implantation bleeding. gentle cramping is additionally the egg implanting itself in the uterine wall.

Congrats on your infant. being pregnant is a very attempting experience, in spite of the undeniable fact that it is likewise mind-blowing!
